This awfuldevice was released in the early 1980s as a futuristic alternative to those antiquated press-button keyboards. All you required to have a key operate was a light brush of your finger on the Touch Sensitive Keyboard - thus avoiding all that prehistoricmanual labour of actually having to press buttons. In practise this keyboard was so touch sensitive it was more or less impossible to actually type anything on it, if you touched "T" then you'd inevitably get the baggage keys of "5", "6", "R", "Y", "F", "G", and "H" if you had mildly big or mildly warm fingers.
